Solved: 451 Temporary internal failure

Service "delivery" at port 24 says the above when one tries to send an internal mail.

Cannot find what causes the error because there is no log of this service. Directory /var/log/gromox ist empty. File /etc/gromox/delivery too.

What can I do? Where can I search?

Thanks in advance!

Solved: Wrong owner of the directory /var/lib/gromox. After "chown -R gromox:gromox /var/lib/gromox" it works.

PCN Distribution?

This issue we see again and again and again.
